Barbarous Radiates, named for their crude nature and emphasis upon the radiate crown worn by the emperor on the prototype, were primarily produced in the western provinces, such as Gaul and Britain, in the centuries following the decline of the empire. Though mostly imitative of Antoniniani of the mid-late third century AD, these coins were generally smaller than the official issues and circulated as small change. Dies were engraved with varying degrees of skill, with the most extreme examples featuring relatively unintelligible legends and generic reverse deity types.
